Smart bath

ABSTRACT

The present invention discloses an entirely mobile system and method for bathing non-ambulatory patients in the more convenient and pleasant environment of the patient&#39;s own bed. The invention consists of a maneuverable cart housing, a clean water supply and all other necessary apparatus and optional accessories for bathing a patient. A key feature of the Smart Bath is a special waterproof and disposable bathing sheet placed over the bed and under the patient which is easily and conveniently manipulated into the shape of a bath.

FIELD OF INVENTION

This invention relates to a bathing cart which contains a waterdispensing and disposal system and all necessary attachments in a singlemobile unit, for bathing bed-ridden patients in the convenience of thepatient's bed where the cart is brought to the patient and a water-proofbathing sheet is placed on the bed in such a fashion that it creates abath.

BACKGROUND OF THE INVENTION

There are currently several methods of cleansing bed-ridden persons. Oneis to “sponge-bathe” the patient while the patient remains in the bed.This does not allow for complete cleaning and, in spite the laborrequired, is an ineffective cleaning method. Another option is to placethe patient in a wheelchair and wheel the chair into the public bathingor shower area, which involves lifting the patient out of the bed andinto the chair. The cleaning received in such a position is notcomfortable for the patient. Furthermore, it is difficult for thecaregiver to give a thorough bath and is not convenient.

Numerous attempts have been made in recent years to provide an effectiveand efficient method of bathing a bed-ridden patient that is alsocomfortable for the patient and practical for the caregiver. There are anumber of patents that mention the possibility of washing orfacilitating the washing of bedridden persons. Prior art methods andtechniques for bathing bed-ridden patients include Japanese PatentNumber JP11319016, which provides a specially equipped bed that allows acaregiver to bathe the patient without wetting the mattress. This isaccomplished by tying a bathtub cloth to an assembled frame in such away that the cloth creates a bathing area; after the bath, thewastewater is drained by releasing a portion of the cloth.

Japanese Patent Number JP4090758 discloses a method of bathing of abed-ridden patient where the patient is enclosed in a bag-likewaterproof enclosure, water is sprayed on the patient through a jetnozzle insertion port, and the wastewater flows out a drain groove andinto a collection reservoir. In a similar technique, Japanese PatentNumber JP4044764 provides a covered waterproof basin within which abedridden person is laid for bathing. Water enters the basin through aninjection hole, and drains out a discharge hole. The water isaccumulated by bending the basin in various places.

European Patent Number EP0491679 describes an automated system thatprovides bed-ridden patients with a means of turning over in bed as wellas moving from the bed to an adjoined bathing tub with minimal or nohelp of an attendant. European Patent Number EP0599123 presents amechanical device for transferring physically handicapped personsbetween a bed and bathtub and for cleaning and attending to them.

U.S. Pat. No. 5,522,099 facilitates the bathing process of bed-riddenpatients by providing a specially designed mattress cover that fits overthe mattress in much the same fashion as a sheet and is sloped so thatthe waste water, accumulated when washing patients in bed, drains off.Similarly, U.S. Pat. No. 4,958,389 is a waterproof sheet that attachesto a hospital bed to facilitate both showering and bathing of bed-riddenpatients. This cover provides a method for containing the water as wellas a drain port to enable convenient disposal of run-off water. Inanother variation, U.S. Pat. No. 6,088,848 is a modular portable showerwith an impermeable liner and a modular frame that allows a bedriddenperson to be showered while lying on bed.

Portable bathing methods are also addressed. U.S. Pat. No. 5,842,238proposes a portable and adjustable cart that slides under a bed and outthe way, equipped with a washstand that is positioned under a patient'shead and is especially suitable washing the hair of bed-ridden persons.U.S. Pat. No. 5,678,257 describes a portable bathing unit that wheels upto the patient's bed where the patient is moved from the bed to the unitfor bathing and then returned to the bed. U.S. Pat. No. 5,539,941presents a portable system designed primarily for lifting patients froma bed and transporting them. In a secondary application, an additionalbathing cart is brought to the bed and used in combination with thelifting device to bathe bed-ridden patients.

All the solutions specified above provide caregivers assistance inbathing bed-ridden patients. However, none of the solutions offeredabove discloses a simple, efficient and portable system for bathing anon-ambulatory patient who is positioned on a bed, which comprises aself-contained unit with all of the components required for bathing saidpatient, including a disposable bathing sheet placed between bed and thepatient, a temperature controlled water source and a wastewater disposalmethod.

BRIEF DESCRIPTION OF DRAWING

FIG. 1: Is a front view of one embodiment of the present invention asseen in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The current invention is a completely portable bathing system thathouses all the items necessary, including a temperature controlled watersupply, for bathing the patient in his own bed. Novel to this inventionis the bathing sheet that allows for creation of a bath right on thepatient's bed. The bath is created by simply placing the waterproofbathing sheet on the bed and the fastening it in such a way that itcreates a bathing space. Assembly is straightforward and uncomplicated.As there is no need for the patient to get out of bed, there is also noneed for the caregiver to lift the patient. The patient can receive aproper bath in the dignity and familiar environment of his own room.

Before use, the cart (1) is connected to a standard wall socket by theelectric cable (2) in order to charge the power source (3). When theservices of the Smart Bath are required, the cart is disconnected fromthe wall socket by unplugging the electric cable. The electric cable isstored on the cart in the designated space. The filling hose (4) isremoved from its storage place and connected at one end to a waterfaucet (5) and at the other end to the water storage tank (6). The waterfaucet is opened and the water storage tank is filled. When the waterlevel indicator (7) located on the side of the water storage tank showsthat the water storage tank has the proper amount of water, the operatorturns the water off, disconnects both ends of the filling hose andreturns the hose to its storage space. The cart is then wheeled intoposition at the foot of the patient's bed.

The bathing sheet (8) can then be attached to the patient's bed. Thebathing sheet is made of any water-impermeable, disposable, or reusablematerial and can be of any shape that is convenient to the shape of thebed, including flat or fitted. The bathing sheet has openings (9) of anyshape located anywhere along each side that correspond to hooks (10)placed along the sides of the bed. The openings on the sheet may haveany type of reinforcement. The hooks may be of any convenient shape andwill match the openings on the bathing sheet. The height and directionof the hooks is adjustable. The hooks are under covers that will helpprevent accidents and injuries. The bathing sheet is placed over the bedand under the patient in a fashion similar to changing the bed sheets.The caregiver first attaches the sheet to the far side of the bed byplacing the openings over the corresponding hooks on the bed and thensmoothes the sheet partially on the bed. The caregiver then rolls thepatient over to the far side of the bed and finishes smoothing out thebathing sheet before rolling the patient back. Finally, the openings onthe near side of the bathing sheet are placed on the corresponding hookson the near side of the bed. At this point, if the sheet is equippedwith drawstrings, the drawstrings will be tightened. Once the bathingsheet is in place, it creates the bath.

After the sheet is in place, the suction hose (11), equipped with adisposable end (12), is removed from its storage space on the cart andis attached to the drain port of the bathing sheet. The other end of thesuction hose leads to the suction device (13), which siphons off theused water and drains it into the wastewater tank (14). The suctiondevice is turned on by an on/off button or switch located either on thecart or on the device or by a foot operated pedal. Alternatively, thesuction hose can lead directly to the wastewater tank.

The rinsing hose (15) with an attached showerhead (16) is removed fromits storage space on the cart and attached to the water storage tankwith either a screw or snap connector. The rinsing hose is equipped witha special temperature-sensing valve to ensure that proper temperaturewater is used. The showerhead may or may not have a handle that allowsthe water pressure to be adjusted. The system is now set up to bathe thepatient.

During the bathing process, water is drawn from the water storage tankthrough the rinsing hose by gravity and/or an attached electronicdevice. Gravity and the suction device continuously transfer the usedwater from the bathing sheet to the wastewater tank. At the end of thebath, the caregiver towels the patient dry. The bathing sheet may haveabsorbent drying materials stored between two layers of the sheet,accessed by opening appropriately located perforations.

Once the bathing process is complete and the wastewater is completelyremoved from the bathing sheet into the wastewater tank, the system isdisassembled, largely the reverse of the previously described assemblyprocess. The suction device is turned off. The drainage and rinsinghoses are detached and returned to their respective storage spaces. Thebathing sheet is unhooked from the bed and deposited in the used bathingsheet container (17). This container may be attached to the cart and mayor may not be quipped with a special sheet shredder that operates onlywhen its top cover is completely closed. The used bathing sheetcontainer may also be equipped with a special weight to press the sheetsdown. The Smart Bath is now ready to be moved to the next patient orreturned to storage to recharge the power source.
